I just ordered a EK-FC5870-Acetal for my 5870. I bought a used ThermoChill PA120.1 and a used swiftech h20-220 radiator. I'm only going to cool the cpu and gpu right now. I can use a radiator for both on its own, wondering what one to use on each. Also, I've got my fans plugged into the motherboard right now and they're flipping on and off like the motherboard is cycling them. Wondering if they're just dying or if the motherboard is doing that. It's definitely hurting my temps crunching.
